A line has an equation of,
.
m is called a slope
n is called y-intercept
We are also given two points .
We begin with computing the slope,
We have computed the slope m and our equation is almost done,
Next step is to find out what y-intercept n is. I will use point and insert x and y it into already known equation, then solve for n,
The reason I can insert coordinates of a point as x and y is because this particular point is in the line described by equation,
Hope this helps. :)
<h2>Division</h2><h3></h3><h3>10 x b = 90</h3><h3>is the same as</h3><h3>b x 10 = 90</h3><h3></h3><h3>divide both sides by 10</h3><h3>b x 10 ÷ 10 = b</h3><h3>90 ÷ 10 = 9</h3><h3></h3><h3>so</h3><h3>b = 9</h3>
√75 = √25*3 = 5<span>√3
the square root of 25 is 5. Therefore you bring it out of the square root and leave the 3</span>
<u>Given </u><u>:</u><u>-</u>
- A function f(x) = - (x -17)/12
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The inverse of the function .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given function is ,
f(x) = -(x-17)/12
Replace y with f(x) ,
y = -(x-17)/12
Interchange x and y ,
x = -(y-17)/12
Solve for y ,
12x = -y +17
y = -12x +17
Replace y with f-¹(x) ,
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>-12x </u><u>+</u><u>1</u><u>7</u><u>.</u>
